Debian: Security update for squirrelmail

Various vulnerabilities have been found in SquirrelMail, a webmail application. SquirrelMail did not prevent page rendering inside a third-party HTML frame, which makes it easier for remote attackers to conduct clickjacking attacks via a crafted web site. Multiple small bugs in SquirrelMail allowed an attacker to inject malicious script into various pages or alter the contents of user preferences. It was possible to inject arbitrary web script or HTML via a crafted STYLE element in an HTML part of an e-mail message. Updated packages are available from security.debian.org.
